| Summary: | 博士 === 國立中興大學 === 昆蟲學系所 === 95 === The family Aphrophoridae of Taiwan was revised taxonomically based on morphological study. The result shows that the so called “tylus” and “clypeus” are located on the dorsal aspect of frons and frontal apex respectively based on anatomy. Besides, several structures could be useful for the diagnosis of different taxonomic ranks between the family, including basiconic sensillum of the flagellum, meracanthus of the midleg, venation of the hindwing, the number of rows of apical spines on the first tarsus, dorsal process of the pygofer, ventral process of the pygofer, aedeagus process in apex, and ventral process of the abdominal segment X. At the present study, 78 species of Aphrophoridae from Taiwan belonging to 17 genera are recognized, with 55 species considered endemic. One new genus and 11 new species are established, including Paramesoptyelus Shih and Yang gen. nov, Aphrophora choui Shih and Yang sp. nov., Jembra taiwana Shih and Yang sp. nov., Hiraphora gloria Shih and Yang sp. nov., Hiraphora fuscata Shih and Yang sp. nov., Peuceptyelus decussatus Shih and Yang sp. nov., Peuceptyelus helvus Shih and Yang sp. nov., Peuceptyelus lini Shih and Yang sp. nov., Peuceptyelus nantouensis Shih and Yang sp. nov., Paramesoptyelus taiwanus Shih and Yang sp. nov., Mesoptyelus kenchini Shih and Yang sp. nov., and Mesoptyelus kuanae Shih and Yang sp. nov. Nokophora nokoensis Matsumura is transferred to the genus Jembrana, Nagaclovia formosana Matsumura transferred to Clovia, Ptyelus tamahonis Matsumura transferred to Mesoptyelus, and Ptyelus vittatus Kato transferred to Mesoptyelus. The genera Megafukia Matsumura, Nokophora Matsumura, and Nagaclovia Matsumura are junior synonyms of Aphropsis Metcalf and Horton, Jembrana Distant, and Clovia Stål respectively. Aphrophora kikuchii (Matsumura) is a junior synonym of Aphrophora karenkoensis Kato. Aphrophora arisanella (Matsumura) is a junior synonyms of Aphrophora taiwana Kato. Megafukia gigas (Kato) is a junior synonym of Aphropsis maxima (Jacobi). Jembrana arisanensis Chou and Liang is a junior synonym of Jembrana nokoensis (Matsumura). Mesoptyelus arisanus Matsumura is a junior synonym of Mesoptyelus fascialis Kato. Philagra kanoi Matsumura is a junior synonym of Philagra arisana Kato. The genera Hiraphora Matsumura and Sinophora Melichar are recorded for the first time. A phenetic analysis of Aphrophoridae of Taiwan is conducted based on 27 characters and 15 aphrophorid genera. The preliminary result indicates that a group contained the genera Clovia, Philagra, Poophilus, and Lepyronia is well supported.
